Whats the study type for an error medication research?

As we all are excited for the JCR list. Please discuss any updates regarding the JCR 2022 list.

How we can identify that some journals can get the impact factor in the upcoming year?

Please share your views about it.

Thanks

I am going to conduct a prospective observational study on the attribution of dispositional factors and rehab interventions to the vocational outcomes of people with mental illness. From literature review, there are about 3 to 4 contributing factors and 2 to 3 dispositional factors (confounders). I've read about the "10 cases for each predictor" rule on the internet. Is it valid? Any software or program can help in calculating the minimal sample size?

1) Does transfer from community hospital to tertiary center for definitive surgical management result in higher mortality rate versus patients in the city?

2) Are the patients who are rurally based experiencing delays to hip fixation compared to urban patients?

Patients: 1241 patients total. 714 patients from the city compared to 527 patients who were transferred in from rural community hospitals.

Mortality: Power 0.8, alpha 0.05, anticipated incidence of mortality in rural group 20% vs 10% in urban group

-199 patients required in each group to achieve the above?

Surgery within 48hrs: Power 0.8, alpha 0.05, anticipated incidence of mortality in rural group 70% vs 90% in urban group

-62 patients sample size required to achieve the above?

Main Outcome: Groups were compared with respect to mortality within 12 months of hip surgery and time to surgery. Subgroup analysis of rural patients based on distance from tertiary centre and mortality / achieving the benchmark of surgical management in 48 hours.

Hi all,

I am stuck at the following problem: I need to determine if there is a significant difference in Length of stay (LOS) in two groups: decendents and survivors, in different age groups. Can somebody help me with this? In a similar article I found they did use kruskal wallis to calculate this. Somebody some ideas to solve this in stata?

Thanks a lot!

Dear Colleagues,

I need to make a literature search using the EMBASE and MEDLINE databases. Do you know how to access the databases using your university VPN?  

I believe my university (UCLA) has access to the databases. However, every time I try to access either of the databases using the VPN, I am directed to a page when I am supposed to subscribe and pay for my access. Any suggestions?

To UCLA folks: I use the Medline VPN which I imagine should have the same access as the UCLA VPN.

Thanks a lot!

Best wishes,

Monika

I’ve performed a study in which 53 subjects each evaluated whether a set of 25 imaging studies was normal or abnormal. I also have the “gold standard” of whether each of the 25 imaging studies was truly normal or abnormal. What is the best way to assess the overall accuracy of the subjects’ evaluations relative to the gold standard? Can I just report gross accuracy (% correct) with a confidence interval? Can I calculate the sensitivity and specificity for each subject and then report the mean sensitivity and specificity?

I don’t want to report inter-rater reliability (kappa, ICC) because it doesn’t matter if the subjects agree with each other, only if they got it right.

Part 2 of this study involves 53 subjects that each evaluated whether a set of 25 imaging studies should be in one of three categories (low, medium, high). The gold standard for the correct category out of 3 is also known for each of the 25 imaging studies. What would be the best way to assess how accurate the subjects were at identifying which category out of 3 each study was in?

Thanks in advance for any advice.

We recently had a case of parasitic pleural effusion demonstrating the microfilaria in pleural fluid, the patient was also diagnosed with lung malignancy. Any free journals?
